本発明は画像信号測定装置に関し、特に印刷する原稿か
ら測定した黒の面積比率のデータを印刷機に出力する画
像信号測定装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image signal measuring device, and more particularly to an image signal measuring device that outputs data on a black area ratio measured from a document to be printed to a printing press.
輪転式印刷機に供給するインク量の制御は、印刷する原
稿から測定した黒の面積比率のデータによって行わうこ
とができる。The amount of ink supplied to the rotary printing press can be controlled using data on the black area ratio measured from the document to be printed.
